Chopped strands of glass fiber reinforced polymerized dicyclopentadiene (p-DCPD) was manufactured and mechanical properties were assessed. For the purpose, a lab-scale long fiber spray-up molding apparatus had been designed and built. Polydicyclopentadiene (p-DCPD) is a crosslinking polymer with a very rigid network structure resulting excellent mechanical and corrosion resistant properties. In this research, the length of the glass fiber roving was cut such that it would be 100 times its critical length. Uniformity of the fiber volume distribution was examined by varying the spray height, glass fiber weight percentage and the fiber length. Mechanical properties were measured for each processing conditions. It was found that tensile strengths of the specimen fabricated with 50 mm glass fiber were higher over the shorter (25 mm) fiber only if sufficient spray height was achieved. It is definitely desirable to use long strands of chopped glass fibers for composite fabrication processes however; a careful manufacturing precaution is required since the effect of the adhesion force between long fibers from the fiber entanglement cannot be ignored.

制造短切玻璃纤维增​​强的聚合双环戊二烯（p-DCPD）股线，并评估其机械性能。为此目的，已经设计并建造了实验室规模的长纤维喷射成型设备。聚二环戊二烯（p-DCPD）是一种交联聚合物，具有非常刚性的网络结构，因此具有出色的机械和耐腐蚀性能。在这项研究中，玻璃纤维粗纱的长度被切割为使其临界长度的100倍。通过改变喷雾高度，玻璃纤维的重量百分比和纤维长度来检查纤维体积分布的均匀性。测量每种加工条件的机械性能。已经发现，只有达到足够的喷雾高度时，用50毫米玻璃纤维制成的样品的拉伸强度才比较短的（25毫米）纤维更高。但是，绝对需要将长切短的玻璃纤维束用于复合材料的制造过程。由于不能忽略纤维缠结引起的长纤维之间的粘合力的影响，因此需要仔细的制造预防措施。
