Abstract:
1. A composite material comprising: (1) a thermosetting composition in an amount of 20 to 70 by weight with respect to the composite material according to the total weight of composite material, the thermosetting composition including a liquid resin composed of carbon and hydrogen elements, and a low-molecular-weight solid allyl resin, more than 60 percent of the liquid resin being vinyl, the molecular weight of the liquid resin being less than 11,000; (2) a fiberglass cloth processed by a coupling agent in an amount of 10 to 60 by weight with respect to the composite material; (3) a powder filler in an amount of 0 to 55 by weight with respect to the composite material; and (4) a cure initiator in an amount of 1 to 3 by weight with respect to the composite material; wherein said liquid resin is in an amount of 30 to 75 by weight with respect to the thermosetting composition, and has 1,2-addition with vinyl; the content of vinyl is preferably more than or equal to 70%; wherein said low-molecular-weight solid allyl resin is in an amount of 25 to 70 by weight with respect to the thermosetting composition, and said low-molecular-weight solid allyl resin is selected from allyl novolac resin, allyl epoxy resin, allyl bisphenol A modified benzoxazine resin, allyl phenol modified benzoxazine resin, allyl cresol modified benzoxazine resin or a combination thereof.
